Installation and use of memcached and Nginx integration memcached

First, the installation of the module starts

wget http://cdnetworks-kr-2.d1.sourceforge.net/project/levent/libevent/libevent-2.0/libevent-2.0.10-stable.tar.gz
wget http://nchc.dl.sourceforge.net/project/levent/libevent/libevent-2.0/libevent-2.0.22-stable.tar.gz

Libevent
./configure
Make
Make install

Vim/etc/ld.so.conf

/usr/local/libevent-2.0.22/lib/
Ldconfig

wget http://memcached.org/files/memcached-1.4.25.tar.gz
Little friends, Fq.
Tar xvf memcached-1.4.25.tar.gz

Third, the Operation method
<command name> <key> <flags> <exiptme> <bytes> [noreply]\r\n
Or
CAS <key> <flags> <exptime> <bytes> <cas unique> [noreply]\r\n

Set stores the specified data;
Add to store data without the <key>;
Replace stores data in the case of a <key>;
Append append data to the tail;
Prepend append data to the header;
INCR/DECR increase or decrease a value

This situation typically occurs when you start the memcached server using the-m parameter, or fail when the entry is clear. Stats Sizesstat the 7STAT< item size > < number of items >

Five, Nginx compilation
Yum install-y zlib-devel gcc gcc-c++
Compile Nginx (slightly)
Nginx configuration is as follows:

Server { location/ {            Set$memcached _key $uri; Memcached_pass127.0.0.1:11211;            Memcached_buffer_size 16k; Memcached_read_timeout30000; Memcached_send_timeout30000; Default_type text/html; #error_page404@fallback; } location @fallback {proxy_pass http://192.168.3.139:8080;        } }
